Secure Phone Calls

[subodhiitk]

Hi everybody...

Can we make secure phone calls from our windows mobile phone ?
Do both the phones have to be windows phone, so that one can encrypt, transmit over cellular line and on the other hand listener can receive that encrypted line, decrypt and then listen ?

Any kind of help will be appreciated !

TIA

A regular phone call still goes through your carrier, which is automatically a voice call. That is done in the radio unit, not in Windows Mobile. On the other hand, you can try and use Skype or something in that fashion using a data connection (3G, UMTS, HSDPA etc).
